You can still buy it at: !! But it comes in 2 parts and you have to mix it yourself. Very helpful also. I don't think I read this source here, but I didn't read every single post either. Just in case: http://www.altcancercream.com/default2.asp
My husband did try it on a rather large skin tag. It was difficult to cover w/bandaid. It got really gross also but one day it turned BLACK!! and eventually fell off. I guess the tag was too large (about 1/2 inch long???) so he had to do it again. Both time it definitely was painful. But it now is just a little bump but always pink. I don't think he wants to try it anymore. He cut off another one that was smaller and that was the easier way to go.
